Patent NL-7212921-A (NL)
IPC: F28F9/00
Filed: 1972-09-25
Abstract: An illustrative embodiment of the invention alleviates the stresses that are caused by the application of relatively cold feedwater to a heat exchanger tube sheet. The colder feedwater that characterizes a low load condition in a nuclear power plant is admitted to the heat exchanger riser chamber that is adjacent to the primary coolant outlet head tube sheet by way of an inlet bypass system. The bypass prevents the thermal shock that otherwise would have resulted from the exposure of the tube sheet on the one side to cold inlet feedwater and, on the other side, to a very hot primary coolant. As the feedwater temperature increases with the power plant load and approaches the primary coolant outlet temperature, the bypass system is turned off. The main feedwater inlet nozzle then discharges into the heat exchanger in an essentially direct fluid communication with the tube sheet.

Title: Cold rolled double tee beam - has double thickness flanges produced by repeated folding of uniform sheet metal strip
IPC: B21D5/08
Filed: 1977-09-30
Abstract: The cold rolled double-Tee beam has a web section (1) and two parallel end sections (2, 3). Each end section is produced by folding the sheet metal once through 90 deg. and twice through 180 deg.. Thus the tapered edge (6, 7) of the sheet metal is in contact with the outside of the 90 deg. radius (2a, 3a). The upper flange (3) of the beam has its edges (5) folded through 90 deg. so that they are parallel and point towards the centre of the profile. This increases the bending strength of the beam about the Y-Y axis and generally improves the stiffness of the profile beam.

Title: Technique, and the associated components, required for the printing process, and preparations for this technique, for a clip for securing or holding together sheets of paper or other materials.
IPC: B41F17/00
Filed: 1993-09-02
Abstract: The invention relates to a plate provided with calibrated holes which are arranged in a fixed pattern in the plate. The plate is made from dimensionally stable material, and one or more clips which are used to secure and/or hold together sheets of paper or other materials can be placed on the plate. The plate, with the clip(s) pushed on, is placed on a template which is provided with pins arranged in the same pattern as the holes in the plate. The template with the pins is arranged on a linked belt which transports the plates with clip(s) past the pads of an inking-pad printing machine. The fact that the holes in the plate are calibrated means that a clip which has been placed on the plate is continuously positioned, with the result that the various print runs carried out for one print are more accurately in register than was hitherto possible using the known inking-pad printing systems and associated components.

Patent PT-95122-A (PT)
Inventor: PARKS DAVID LEORY JR
IPC: C07C201/08
Filed: 1990-08-28
Abstract: This invention relates to an improved process for the recovery and regeneration of nitric acid from spent acid obtained from the mixed acid nitration of aromatic compounds. In that process a mixed acid of sulfuric acid and nitric acid is contacted with an aromatic composition at a temperature and pressure sufficient for producing a nitroaromatic composition and a spent acid containing unreacted nitric acid, sulfuric acid and solublized nitroaromatic compounds in said spent acid. The improvement comprises initially heating the spent acid to a temperature of from about 120 to 200 DEG C for a time sufficient to convert said nitroaromatics in said spent acid to a nitroaromatic composition having a boiling point greater than 300 DEG C at atmospheric pressure and then flash distilling the hot spent acid containing nitroaromatics compositions at a pressure from about 5 to 15 psia and temperature of 150 to 200 DEG C. Nitric acid is removed as an overhead vapor fraction in preselected concentration and sulfuric acid and nitroaromatics are obtained as a bottoms liquid stream from said flash distilling step. The nitroaromatics are then removed from the liquid stream. Sulfuric acid obtained from this process is essentially free of color and suited for concentration.
